Steel Mezzanine Fabrication Caldwell Idaho — Industrial Platforms & Warehouse Expansion

We design and fabricate steel mezzanines and industrial platforms for warehouses, manufacturing facilities, and distribution centers across the Treasure Valley. If you've got 24-foot clear height and you're only using the bottom 10 feet, a mezzanine is the fastest way to double your usable space without pouring a new foundation. We build them in our Caldwell shop, deliver in 3–6 weeks, and install in 2–5 days.

The Math: Mezzanine vs. New Construction

Building new warehouse space in Canyon County is a major investment — land, foundation, shell, permitting, and 6–12 months of construction. A mezzanine inside your existing facility costs a fraction of new construction and installs in weeks, not months. For a typical 10,000 SF warehouse with adequate clear height, a mezzanine adds 4,000–6,000 SF of usable space.

• Cost per SF: A fraction of new construction
• Timeline: 3–6 weeks vs. 6–12 months
• ROI: Fast payback — contact us for a quote on your specific space
• Flexibility: Mezzanines can be relocated or expanded — new buildings can't

What We Build

We fabricate three primary mezzanine configurations, each engineered for specific load cases:

Structural Steel Mezzanine

• Best for: Heavy manufacturing, equipment platforms, production expansion
• Span: 20–40 feet clear span between columns
• Load capacity: 250–500 PSF
• Deck options: Diamond plate, concrete-filled pan, bar grating

Rack-Supported Mezzanine

• Best for: Warehouse storage, distribution, pick modules
• Span: 8–12 feet (bay spacing of pallet racking)
• Load capacity: 150–300 PSF
• Cost advantage: 15–25% less than structural steel

Free-Standing Mezzanine

• Best for: Flexible or relocatable applications, modular facilities
• Span: 10–30 feet
• Load capacity: 125–250 PSF
• Key feature: No attachment to existing structure — fully self-supporting

Our Engineering and Fabrication Process

Every mezzanine we build goes through a full engineering cycle before we cut steel:

• Site survey and load analysis: We come to your facility, measure clear heights, column locations, and floor slab capacity. If your slab can't handle the mezzanine loads, we design the foundation pads.
• Structural engineering: Our engineers design beam sizes, column spacing, connections, and deflection limits for your specific application. All designs account for Canyon County's Seismic Design Category C (0.42g SDS).
• CNC fabrication: All beam blanks, deck pan, stair stringers, and connection hardware get cut on our plasma table and formed on our 150-ton press brake. ±1/16\" tolerance on every piece.
• OSHA guardrail integration: Guardrails, toe boards, and self-closing gates are part of the package — not an add-on. 42-inch top rail, 21-inch mid-rail, 4-inch toe board, all per OSHA 1910.23.
• Delivery and installation: We coordinate delivery to your facility and our crew handles installation. Standard mezzanines install in 2–5 days. We work nights and weekends if your operation can't shut down.

Compliance: OSHA and IBC

We engineer every mezzanine to meet both OSHA and IBC requirements from day one — not as a retrofit:

• OSHA 1910.23: 42\" guardrails, mid-rails, toe boards, 250 lb load ratings
• IBC Chapter 5: Mezzanine stays within 50% of floor area to maintain "mezzanine" classification (avoiding full-story requirements)
• IBC Chapter 16: Structural design per ASCE 7, including seismic base shear for Canyon County
• Deflection limits: L/360 for office, L/240 for storage, L/480 for precision equipment

Deck Material Options

• B-Deck (corrugated): 1.5\"–3\" depth, 150–300 PSF — standard for storage and office mezzanines
• Diamond plate: 3/16\"–3/8\" thick, 250–500 PSF — heavy equipment platforms and industrial use
• Bar grating: 1\"–1.5\" depth, 150–250 PSF — wet environments and areas requiring ventilation
• Concrete-filled pan: 2.5\"–4\" concrete, 250–500 PSF — office mezzanines and sound insulation
• Resin deck / composite: 1.5\" thick, 125–200 PSF — pick modules and distribution

Project Types & Typical Timelines

Here are the types of mezzanine projects we deliver — your actual quote depends on load requirements, deck type, and site conditions:

• Basic storage mezzanine (20'×30', 600 SF): 3–4 weeks
• Standard warehouse (30'×50', 1,500 SF): 3–5 weeks
• Large distribution (40'×80', 3,200 SF): 4–6 weeks
• Office mezzanine, concrete fill (20'×40', 800 SF): 4–5 weeks
• Heavy equipment platform (15'×20', 300 SF): 3–4 weeks
• Integrated stair system: Included in project scope
• Guardrail system: Included in project scope

Facility Types We Serve

• Warehouses and distribution: Storage mezzanines, pick modules, pack-and-ship platforms
• Manufacturing: Equipment platforms, maintenance mezzanines, production expansion
• Retail and wholesale: Back-of-house storage, stockroom mezzanines
• Agricultural: Equipment storage, hay/feed loft mezzanines
• Aviation: Hangar maintenance platforms, parts storage
• Municipal: Equipment storage, maintenance platforms for public facilities

Ready to Expand Your Warehouse?

If you've got clear height you're not using, a mezzanine is the fastest ROI in industrial construction. Contact our engineering team with your facility dimensions and what you need to store or build on the platform — we'll spec the system, handle the engineering, and get it fabricated and installed in 3–6 weeks.
